# Many AIs on one number

> How your reply finds the AI it is for.

All your AIs write from the same WhatsApp number. zapbip decides where your message goes, in this order:

| You do | It goes to |
| - | - |
| Tap a button or a list option | The AI that asked |
| Reply to a message, or react to it | The AI that sent that message |
| Write `@grok check the news` | Grok, without the `@grok ` |
| Answer while one AI has a question open | That AI |
| Write after only Claude spoke | Claude, the last AI that wrote |
| Write when nothing matches | A list of recent AIs to pick from |

## Example

WhatsApp: zapbip

`@claude thanks` goes to Claude and the tap on Yes goes to Grok.

WhatsApp: zapbip

A plain `ok` gets a list of recent AIs to pick from.

Reply to a message to talk to the AI that sent it:

WhatsApp: zapbip

Names have up to 20 characters: lowercase letters, digits and hyphens.
